In PlotIndexSetInteger(), what does the first parameter mean?

New comment
 

In the document here, it says the first param is the Index of the graphical plotting. Graphic plotting is one of the ENUM_DRAW_TYPE. 

 

Why it is always 0 in the example here? I think it should be one of the ENUM_DRAW_TYPE. Why it is not? 

               PlotIndexSetInteger(0,PLOT_LINE_COLOR,0,clrRed);
               PlotIndexSetInteger(0,PLOT_LINE_COLOR,1,clrBlue);
               PlotIndexSetInteger(0,PLOT_LINE_COLOR,2,clrGreen);

The documentation say :

plot_index

[in]  Index of the graphical plotting

It's an int not an enum.

//---- plot ColorLine
#property indicator_label1  "ColorLine"
#property indicator_type1   DRAW_COLOR_LINE
#property indicator_color1  clrRed,clrGreen,clrBlue

The plot is a colorline : 1 plot, 2 buffers. So a colored line with 3 colors. The code you posted set the 3 colors for the plot 1 (indexed as 0).
